the ph of rainwater varies according to your location.
im thinking it would be slighty aciditic tho... somewhere n the 4-5 range

In most cases rain water is better for your plant then tap water, reason being is rain water has a lower PPM then tap water. The PH is also usually better, in my area its about 7.0 PH and 20'ish PPM, I like my PH around 6.5 so I adjust the PH a bit. If you do intend on using rain water might wanna start saving up alot plants get thirsty later on in life

ok thanks ima go collect few gallons lol
